This invention relates to a new and useful device in the nature of. a propulsion device for boats, operated by an internal combustion motor.

. The object of theinvention is to. provide a propulsion device of novel construction and arrangement of parts hereinafter more fully described, claimed and illustrated in the accompanying drawing.

Fig. 1 .is a top plan View of my improved propulsion device. a

Fig. 2 is a transverse sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a side elevational view thereof.

V Fig. 4 is a top plan view of a boat equipped with my'improved device.

Fig. 5, is a side elevational view thereof. ,As here embodied my improved device comprises a lazy tongconsist ing of a plurality of bars 10 and 11 crossing each other centrally and pivotcchas at 11. and 11 are formed or bent curved, as clearly shown inyFig. 1. The bars 10 and 11 are pivotally secured to each other as at 12. The

lazy tong is pivotally attached, at its center as at 13, at one sidethereof, adjacenttothe base 14, to the bracket 15 secured to and extended from the said base. The lazy tong is pivotally attached, at its center, opposite 0 the bracket 15, by the pin 16, provided with an enlarged headfto which is pivotally attachedyas at 17, the rod 18. The rod 18 1s pivotally attached,at its other extremity, to

the I eccentric pin 19, secured to. the rim, of

a; the fly wheel, 20, of an internal combustion motor 21." The internalxcombustion motor 21. is of usual construction, of any desired design and construction, preferably of the four cycle type, of one or more cylinders.

The bars 10 and llare provided with plIlS 23, or extended 'elements, extended angu larly therefrom, in one common direction. At the front ofthe lazy tong structure there are short bars 10 and 11! pivotally connected to each other at their front tips as at 24 and at the rear of the lazy tonguestructure bars 10 and 11 are left with free rear extremities 25 and 26.

The above described construction is such as will permit the lazytong to be opened'or closed, horizontally, when the internal com bustion motor 21 is operated, so as .to cause the pins 23, to propel or drive t heboat to.

which my improved device is attached. The

propelling cycle is accomplished by the dos ing or depressing of the said lazy tong.

scribed construction is such as will permit 1 the motor 21, to be positioned so as to allow the rod 18, to be extended at a right angle to the lazy tong member, from the pin 16,

as shown in Fig. 1 or permit the said rod 18,

to be similarly extended from a similar pin not'shown in the'accompanying drawing, secured to the free rear extremity'25 of the lazy tong, positioned in the aperture 34 The latter described conto .be operated from the rear portion thereof. The rod 35, is securedto the platform 28 and isextended downwardly therefrom throughan elongated aperture 36, formed in the base 14. The hand wheel 37, is threadedly attached to the extended extremity of the rod 35, and is adapted to engage the base 14, so as to hold the motor 21in the above described desired position.

- Having thus described my'invention, what I ,cla1m as new and-desireto protect by Letters Patent of the United States is as follows:

. 1; In a propulsion device of the class. de-l scribed, an internal combustion engine mounted on a platform, wheels secured to the said platform, said Wheels adapted to'engage tracks secured to a base, a lazy tong piVo *tally attached, at its centerto a" bracket secured to the said base, a rod pivotally at,

tached tothe opposite center portion ofthe said lazy tong, said rod beingpivotallyat tached to an eccentric pin secured to the rim of the fly Wheel of the said internal combustion motor.

2. In a propulsion device of the class de-. scribed, an internal combustion 'engine mounted on aplatform, wheels secured to the said platform,..-said Wheels adapted to engagetracks secured to a base, a lazy tong attached at its center to a bracket secured to the said base, a rod pivotallyattached to the opposite center portion of the said lazy tong, said rod being pivotally attached to an eccentricpin secured to the rim of the fly Wheel of the said internal. combustion motor. I V

3. In a propulsion device ofthe class described, an internal iuo no N combustion engine mounted on a platiorm, Wheels secured to the said platform, said Wheels adapted to engage tracks secured to a base, a lazy tong pivot-ally attached atits center to a bracket secured to the said base, a pin pivotally attached to the opposite center portion of the said lazy tong, a rod pivot-ally attached to the pin, said rod being pivotally attached to an eccentric pin secured to the rim of the fly wheel of the said internal COJTlbUStiOll motor.

In testimony whereof I have afiixed my signature.
